如何使用angular.js-resource启用cors请求

Question

我有一个angular.js应用程序,我需要做CORS请求.

我想使用角度资源定义我的休息服务"angular",如下所述:http://docs.angularjs.org/tutorial/step_11.

但我还没有找到办法让这个工作.在谷歌上我发现了以下示例代码:http://jsfiddle.net/ricardohbin/E3YEt/,但这似乎不适用于角度资源.

这是我的app.js

'use strict';

angular.module('corsClientAngularApp', ['helloServices'])
  .config(function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  });

这是我的services.js与其他服务

angular.module('helloServices', ['ngResource']).
    factory('Hello', function($resource){
  return $resource('http://localhost:8080/cors-server/hello/:name', {}, {
    query: {method:'GET', params:{name:'name'}, isArray:false}
  });
});

这是我的main.js与控制器使用$ http,这是有效的!:

'use strict';

angular.module('corsClientAngularApp')
  .controller('MainCtrl', function ($scope, $http, Hello) {
    $http.defaults.useXDomain = true;


    $http.get('http://localhost:8080/cors-server/hello/stijn')
        .success(function(data) {
            $scope.hello = data;
        });
  });

这是我使用角度资源的main.js的另一个版本.这不起作用:(

'use strict';

angular.module('corsClientAngularApp')
  .controller('MainCtrl', function ($scope, $http, Hello) {
    $http.defaults.useXDomain = true;
    $scope.hello = Hello.query({name:'stijn'});
  });

这是来自工作请求的标题(来自chrome devtools):

使用angular-resources时,看起来请求url是错误的.但为什么？

谢谢!

Answer 1

$resource使用冒号接受参数的URL .因此,在url中使用port时,需要将冒号转义为端口.这在$ resource docs中有解释
